Knowing which way the wind is blowing.

Wind power systems must operate at near 100 % availability – hence quality and reliability are extremely important.

Variable-speed, pitch-controlled systems are the current state-of-the-art in wind energy system construction. They can be efficiently deployed in the harsh conditions prevalent in both onshore and off-shore operations.

Build on SICK‘s compe-tence – a competence demonstrated by over ten years’ experience in this sector and more than 20,000 encoders installed in pitch-controlled systems.

Absolute encoder A3M60 – built to last.

The A3M60 is an extremely robust absolute multiturn encoder in a 60 mm housing. Even under the harshest environmental conditions both onshore and offshore, the multi-turn encoder achieves maximum reliability via its magnetic, and thus extre-

mely robust, scanning func-tion. The innovative and gearless multiturn techno-logy reduces the number of moveable parts on the A3M60 to a minimum. This results in a longer service life with reduced mainte-nance requirements.

Absolute encoder AFM60 – the wonder of precision.

With 30-bit resolution and a high level of robustness, the new absolute multiturn encoder AFM60 sets a new record. Even its little brother – the absolute singleturn encoder AFS60 – impressive due to its high 18-bit resolution, counts as one of the best products in its


market segment. The single resolution, as well as the zero point or offset are programmable.The two new product fami-lies are especially suitable for application in the harsh conditions prevalent in wind power systems – in other words, when the highest levels of accuracy and availability are called for.

Absolute encoder ATM60 – the classic design.

The absolute multiturn encoders ATM60 are imple-mented using mechanical drives – they deliver the revolution information very reliably and free from inter-ference. The principle of operation is such that a sensor scans permanent magnetic elements

arranged on a magnetic scale. This makes high precision possible due to the high base resolution of 8,192 steps per revolution.


Extremely robust and extremely precise.

incremental encoder dgs35 – the robust design.

The incremental encoders DGS35 are used in the harshest conditions across the globe. The stable design with an enclosure rating of up to IP 66 ensures for a robust but nevertheless high-resolution incremental encoder. Equipped with a through hollow shaft with a maximum diameter of 30 mm, the DGS family is suitable for use in every application.

incremental encoder dFs60 – the rotary design.

The DFS60 is a high-reso-lution incremental encoder in a 60 mm design. The DFS60 is unique in its class with a maximum number of lines as high as 65,536. Excellent concentricity and exceptional robustness are achieved thanks to the large distance between the ball bearings which support the encoder shaft. The DFS60 is therefore pre-destined for application in wind power systems.

A mechanical interface for all relevant electronic encoder interfaces:incremental (DFS60), absolute (AFS/AFM60) and motor feedback systems (SFS/SFM60).

Motor feedback systems sFs60, sFM60 with HipErFACE® interface.

HIPERFACE® motor feed-back systems comprise a combination of incremen-tal and absolute encoders, successfully uniting the advantages of both enco-der types. They are parti-cularly suited for absolute position finding, with the number of steps being 32,768 per revolution and with a maximum of 4,096 revolutions – that gives

a total resolution of 134,217,728 steps in the case of the multiturn design. The speed moni-toring function is enabled via sine/cosine signals. The storing of motor-spe-cific data in the electronic type label as well as the programming function are further important features of these series. The HIPERFACE® inter-face, which is used in applications across the globe, facilitates the com-missioning of these motor feedback systems.
